Available decoders

Available Decoders

A wide variety of high-performance real-time decoders are available for the evaluation of the interferometric measuring signals. The Optomet UltraDSP technology enables the measurement of frequencies up to 25 MHz and vibrational velocities up to 25 m/s with the Fiber-Series, displacements can be resolved to less than 100 fm. All vibrometers incorporate a velocity decoder, and displacement and acceleration decoders are optionally available. Numerous measuring ranges per decoder ensure that measurements can always be performed with the optimum sensitivity.

Decoders can be easily retrofitted or upgraded. Start with a basic system and adapt the capabilities of the measuring instrument as required. This requires no return of the instrument to the factory and no waiting times for your production or research project. The table below provides an overview of the configuration options. We will also be happy to assist you in the selection of the best decoder for your measuring task.
